I've had good success. If you bought finished decals from Tom Morris and had problems, then perhaps it was your handling? Or did you buy decal paper?
At any rate -- I used decal paper from some coffee cup company. I just followed the directions and had success. My only mistake was buying matt-finish lacquer; the matt-finish was accomplished in a way that printed through the dope I painted over the decal, and required some careful sanding to smooth things out.
